The Case of the Vanishing Starbucks Hotspots – SOLVED

Well, I finally learned why I could not see a T-Mobile SSID and connect to T-Mobile hotspots in local Starbucks locations. See my MobileAppsToday blog for the details. The short answer: Although T-Mobile hotspot tech support says their SSIDs are visible, they are, in fact, invisible. So, I had to manually create WiFi profiles for it on each of my devices. The tmobile SSID was visible as of last month (July).
